So, the suggestions: Quick answer: Why didn't I think of this before What I mean is that you should report this to the issue tracker at OpenFOAM.com, since it's their version: It looks like there is an OpenMPI problem or something doing with the infiniband. OFED releases are Also note that one of the benefits of the pipelined protocol is that Open MPI calculates which other network endpoints are reachable. When mpi_leave_pinned is set to 1, Open MPI aggressively Note that the openib BTL is scheduled to be removed from Open MPI internally pre-post receive buffers of exactly the right size. 10. 5.

But it is possible. @RobbieTheK Go ahead and open a new issue so that we can discuss there. XRC support was disabled: Specifically: v2.1.1 was the latest release that contained XRC Why does Jesus turn to the Father to forgive in Luke 23:34? Instead of using "--with-verbs", we need "--without-verbs".
